Abstract

Traditionally, Miner Extractable Value (MEV) has been viewed as a challenge, where miners or validators exploit arbitrage opportunities through creative block production techniques. The options have been to either combat MEV by limiting opportunities or to embrace it by introducing fairness into block production politics. This paper explores a third approach: leveraging the concept of time in blockchain transactions. By transitioning from a sequential model to a flexible time model, we can engineer radical new transaction semantics. These new spatio-temporal dimensions of MEV-inspired transactions framework opens up novel possibilities for building L1.5 technologies, and of creating hybrid Dapps by leveraging MEV-time Oracles.
